To all whom it' may concern.'

Be it known that l, HERBERT E. KEELER, a citizen ot the United States, and resident of New York city, county of Kings, and State of New York, have made a certain new and useful invention Relating to Stayloilers for Car-Deens, etc., of which the following is a specification, taken in connection with the accompanying drawing, forming a part of the same.

This invention relates to stay rollers adapted for use with sliding doors for railway cars and other purposes and relates especially to stay rollers comprising a curved or retlexed inclosing attaching spring having integral attaching means adjacentone end and having integral bearing members adjacent its tree end to pivotally support the roll which is substantiallT inclosed and irotected by this spring.

ln the accompanying drawing showing in a somewhat diagrammatic manner illustrative embodiments orp this invention in which the saine reference numeral refers to similar parts in the several igures, Figure l is a horizontal sectional view showing one form or' the device applied to a door. F ig. 2 is a transverse sectional view ot the saine taken substantially along the lines 2-2 of Fig. l. Figs. 8, Ll, 5 and G are corresponding hori- Zontal sectional views showing other forms of the device applied to doors or the like.

n the illustrative embodiment ot this invention shown in Figs. l and 2 the roll l ot hard wood, metal or other suitable material preferably having a slightly curved tread as indicated in F ig. 2, may be mounted in any desired way in the roll brackets 3 as by providing a suitable bearing sleeve 22, which may project slightly beyond the ends ot the roll and be supported by the pin or pivot o which may be riveted or otherwise secured to the brackets 3. These brackets may, it desired, be formed integral with the supporting spring 4L or" resilient sheet brass, phosphor bronze or other suitable material, these brackets or integral bearing mevnbers being preferably formed adjacent the tree end of the spring by bending up suitable projections or lateral extensionsv of the spring. Suitable attaching' means may be used to secure the other end of the spring 4 to the door jamb or other support adjacent the door and such attaching means may, if desired, be in the form of integral ears 5 adjacent the end of the spring and formed with holes 6, through which the attaching screws are adapted to engage. The spring may be formed with an outer inclosing convolution comprising the curve i0 to coperate with the door j amb and portions ll, l2 and 13, the curve la thus being located sutliciently near the door to properly protect the roll and prevent material being drawn thereunder. lili desired, also, the spring may be retlezied to form another inner convolution substantially parallel to the outer inclosing convolution or part ot the saine; such convolution being indicated in Fig. l as comprising portions 15, 16 and l?. A still further convolution comprising the parts i8, i9 may, it desired, be formed within the portion 17 and substantially parallel thereto and have the roll brackets 3 and the integral transverse aliners 20 formed thereon. These aliners as indicated in F ig. 2, may extend adjacent to the lateral edges of the spring portions 17, 19, so as to prevent their getting out of alinement and be formed w'th the adjustable stop ears 2i adapted to cooperate with the portieri 1l of the spring in case the roll forces the same outward to an excessive extent so as to increase the spring resistance and prevent the door becoming unduly displaced in a lateral direction. it is ot course understood, thattle stop ears may be readily adjusted by bending the same so as to regulate the extent ot movement of the roll required to bring them into operative engagement with the outer portion ll ot' the attaching spring'.

The illustrative form of device shown in F ig. S embodies a similar roll l mounted on the pin 2 in the roll brackets 3 which may be formed integral with the inclosing attaching spring which may have integral attaching ears 5 at its other end by which the device may be secured by suitable means such as the attaching screws to the door jamb 8. The curved inclosing portion of the spring 3l, 82 and 33, serves to substantially inclose and protect the roll and the downward extending retlexed portion of the spring 23, 24 and 25, gives additional resiliency and may be joined by the curved portion 30 with the free end ot the spring. Suitable adjustable stop and alining means may be provided if desired, by forming suitable elongated slots 35, 36, in the retlexed portion ot the spring with which the stop member or screw 3e engages, thus holding the parts against lateral displacement by (JFT) engagement with the sides of the slots, as Well as limiting the extent to Which the spring yields and increasing the intensity of action of the spring as soon as the portion 25 engages the head of the screw.

In the illustrative form of device shown in F ig. Ll, similar roll l is mounted on the pin 2 in suitable bearing members such as the integral roll brackets 3 on the free end- 4-1 of the attaching and inclesing spring. The portion 39, a0, il of the spring may serve as indicated, to substantially inclose and' protect the roll Whenin operation and suitable attaching means such as the integral ears 5 may be provided at the other end of tne spring to attach the saine to the door jamb or other adjacent support in connection With suitable members such as the screws 7. rlhis attached end 37 of the spring is indicated as having a curved connection with the inclosin-g curved convolution of the spring around the roll. A similar device is indicated in Fig. 5, the curved inclosing convolution of the spring 4S, 49, 50, being indicated as provided with the integral roll brackets 3 supporting the pin 2 and roll l for coperationwith the door or similar member. rlfhe attaching ears 5 are joined in this instance With the inclosingl convolutions by the reflexed portions 4t2, 43, 44:, 45 and 46 of the spring, thus giving additional resiliency7 thereto. in Fig. 6 the somewhat similar inclosing convolution 54C, 55, 56, is shown adjacent the free end of the spring, supporting the roll l, a retlexed portion 51, 52, 53, being arranged for compact mounting adjacent the j amb of the door, the convolution lying Within a suitable recess 58 in the jamb itself to further econoinize space and limit the projection of the stay roller beyond the jamb.

Havingy described this invention in connection with a number of illustrative enibodiments and proportions to the details of which disclosure the invention is not of course to be limited, what is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims.

l. ln stay rollers, a roll, a bearing'sleeve in said roll, a pivot pin extending through said roll and sleeve, a curved reflexed inclosing attaching spring having integral attaching means adjacent one end and integral bearing members adjacent its free end to support said pin, said spring comprising an outer inclosing convolution and reflexed inner substantially parallel convolutions, t'ansverse aliners having adjustable stop ears attached to said spring to maintain the substantial alinement of the convolutions thereof and to coperate with said spring to limit the resiliency thereof.

2. ln st( y rollers, a rol-l, a pin, a curved inclosing attaching spring having attaching mean-s adjacent cneend and integral bearing members adjacent its free end to support said pin and adjustable stop and alining means for said spring.

3. In stay rollers, a roll, a refleXed inclosing attaching spring substantially inclosing and protecting said roll and having` substantially parallel inner and ut-er ccnvolutions and integral bearing members adjacent its free end to pivotally support said roll and attaching means adjacent the other end of said spring.

t. ln stay rollers, a roll, a curved protecting attaching spring protecting said rollV and having integral bearing members adjacent its free end to pivotally support said roll and attaching means adjacent the other end of said spring.

5. in stay rollers, rotary bearing means and a curved protecting attachingl spring protecting said bearing means and having bearing members adjacent its free end to ,.upport said bearing means and attaching means adjacent the other end of said spring.

G. in stay rollers, a roll and a curved inclosing attaching spring having integral attaching means acent one end and integral bearing members adjacent its free end to pivotally support said roll.
